Madame de Pompadour 

This pastel portrait of Madame de Pompadour, the mistress of King Louis XV, was created by Maurice Quentin de La Tour, a leading portrait artist of the Rococo period. The artist was known for his use of pastels to achieve a soft and delicate effect, as seen in this work's subtle shading and highlights. De La Tour's masterful use of pastel allows him to capture the sitter's delicate features and gentle expression. The portrait is a striking example of the Rococo style's emphasis on elegance, grace, and sensuality.
